Pacing signal processing method, system and electrocardiogram monitor

Abstract

A pacing signal processing method, a system and an electrocardiogram (ECG) monitor, the method includes collecting at a high sampling rate the original ECG signal from a surface, obtaining the parameter and position information of a pacing signal according to the sampling points, and displaying the pacing signal morphology and / or parameter information of the pacing signal.

Description

TECHNICAL FIELD[0001]The disclosure relates to the field of medical care, and in particular to an electrocardiogram (ECG) monitor, as well as a method and a system for cardiac pacing signal processing.BACKGROUND ART[0002]A cardiac pacemaker (“pacemaker”) is an electronic therapeutic instrument implanted in the body for treating cardiac dysfunctions caused by certain arrhythmias. In operation, it releases electric pulses energized by a battery by means of a pulse generator to stimulate the cardiac muscles in contact with wired electrodes. For a patient having a pacemaker implanted in his or her heart, it is necessary to check the operational status of the pacemaker. Since the pacemaker can transmit wireless signals, a special test device (e.g., a programmer) may be used to wirelessly receive various operating parameters of the pacemaker and the ECG pacing pulse waveforms in the body, after which an evaluation on the operating state of the pacemaker and an adjustment on the pacemaker'...

AI Technical Summary

Benefits of technology

The patent describes a method for smoothing pacing signals in ECG signals to remove the pacing signal while keeping the main components of the ECG signal. The method is adaptive, meaning it can automatically adjust the pacing smoothing width based on the conditions of different patients' pacemakers. This results in a more effective process that helps to maintain the effective component of the ECG signal.

Problems solved by technology

However, since pacemakers are produced by different manufactures, they are not applicable to a same type of programmers, and thus the pacing morphology, the parameter information, as well as the operating status of the instrument and accessories are not available unless the model of pacemaker is known and then the corresponding programmer detection device is determined.

Although this solution can provide evaluation, configuration, and adjustment of operating parameters of a pacemaker and can directly monitor the pacemaker, the process is troublesome and cannot be easily used for screening and monitoring.

The conventional pacing pulse detection can only show whether the pacemaker has been triggered, and cannot distinguish biatrial or biventricular pacing or gain any more information, such as morphology, width, height, polarity, duration and so on of the pacemaker.

Therefore, it is not possible to convincingly distinguish interference from the pacing pulses, causing medical care personnel to sometimes doubt about the accuracy of the information concerning the pacemaker's operating status.
